PUZZLE.

Specification of Letters Patent.

Patented Aug. 26,1913.

Application filed February 15, 1913. Serial No. 748,556.

To all whom it may concern Be it known that I, JOHN A. DrrroLo, a citizen of the United States, residing at New Haven, in the county of New Haven and State of Connecticut, have invented a new and useful Improvement in Puzzles; and I do hereby declare the following, when taken in connection with the accompanying drawings and the characters of reference marked thereon, to be a full, clear, and eX- act description of the same, and which said drawings constitute part of this applicatien, and represent, in

Figure 1 a face view of a puzzle constructed in accordance with my invention. Fig. 2 a sectional view of the same. Fig. 3 a view of the strap or loop, detached. Fig. 4 a sectional view showing the strap in the disengaged position.

This invention relates to animprovement in puzzles, and particularly to puzzles including a disk or plate connected with a strap or loop, and in which the puzzle is to disconnect the disk from the loop or strap.

The object of this invention is to so connect a loop or strap with two disks as to make the separation obscure or difficult; and the invention consists in the construction hereinafter described and particularly recited in the claim.

In carrying out my invention, I employ two disks or plates 2, 3, round or any other shape, and preferably formed from metal. The plate 2 has three parallel slots 4, 5 and 6, and the plate 3 has three corresponding parallel slots 7, S and 9. IVith these plates I employ a strap 10 formed at one end with a slot 11 and the opposite end with a slot 12. It is apparent, without further illustration, that the inner ends of the slots might be connected so as to form a single slot, or a strap might be replaced by a cord the ends of which are connected together. \Vhen the strap is connected with the disk the end 13 rests upon the face of the disk covering the slot 5. The strap then extends from front to rear through the slot 4. downward, and from rear to front through the slot 5, and through the slot 11 in the strap, thence downward and from front to rear through the slot 6, then from rear to front through the slot 7, through the slot 12 in the strap, and from front to rear through the slot 8, from rear to front through the slot 9, and downward over the face of the slot 8 where the strap passes through the slot 12. The strap is thus firmly interlocked with both disks. To separate the strap from one of the disks the strap is drawn upward through the slot 6 to a suflicient extent so that the end 13 may be carried down and passed from front to rear through the slot 6 until the end 13 projects so far beyond the slot 6 as to enable the disk 3 to be passed through the slot 11. hen passed through the slot 11 the end 13 may be drawn back through the slot 6, and readily drawn through the other slot so as to separate the disk 2 from the strap.

It will be understood that either disk may be separated from the strap in the manner before described. WVhen one. disk is separated, it is obviously easy to separate the other disk. The disk is replaced by reversing the operation above described. As the strap is threaded through the three slots of each disk, it is apparently a very difficult proposition to detach one of the disks. These disks or plates may form convenient surfaces for the application of advertising matter.

I claim A puzzle comprising two disks each formed with three slots combined with a strap having a loop at opposite ends, the ends of the strap threaded through the three slots in the respective disks, and the body of the strap passing through the loops at its ends whereby the disks are attached to opposite ends of the strap.

In testimony whereof, I have signed this specification in the presence of two subscribing witnesses.

JOHN A. DIPPOLD.
